Average Fall Color

The MN DNR has put together a nice graphic that shows typical dates for peak fall color. The northern par of the state starts to peak during the 2nd half of September into early October. Meanwhile, folks in the central part of the state and into the metro typically don't see peak color until the end of September into the middle part of October. It won't be long now - enjoy!

What Causes Fall Colors?

The chemicals - Four main groups of biochemicals are responsible for the various yellows, oranges, reds and browns that we see in the fall: Chlorophyll, Carotenoids, Anthocyanins, Tannins. Each has its own color and chemistry. As the amount of these chemicals vary, they will cause subtle variations in color from one leaf to the next, or even from tree to tree.

The Extended Outlook Calls For Cold Fronts
By Paul Douglas

Predicting the future with a modicum of accuracy and reliability is not for the faint of heart. An anonymous TV anchorman once scolded me for a blown forecast. Off the air I told him the truth: you can dress a monkey in a sport coat to tell people what already happened. Try predicting the news - or sports scores! Then we'll be on a level playing field. He ignored me but that's okay.

The next 6 months will bring cold fronts of various sizes and intensities. Yesterday's summer mirage gives way to wind-whipped showers and sprinkles today and Thursday. Far northern Minnesota may see a coating of slush by Sunday, but the metro remains flake-free until further notice. No more 80s, but I suspect we'll pick up more 60s, maybe a 70 or two.

According to NOAA, Hurricane Ian was the 15th billion-dollar disaster of 2022. Modeling firm RMS projects damage between $53 billion and $74 billion. The personal loss is incalculable.

Update: I've retired my shorts for at least 6months. With luck I'll still fit in them come '23.

Climate Stories

"How climate change is shifting the water cycle"

"What is the water cycle? Put simply, the water cycle — also known as the hydrological cycle — is the process by which water moves through the Earth's land, seas and atmosphere. Water in its three natural phases, be it gas, liquid or solid, forms part of the natural cycle that continuously refreshes the supply of water that we, and every other living thing, need to survive. Of the world's finite supply of water, around 97% is salty. The remaining 3% is fresh water which we use for things like drinking, bathing or irrigating crops. Most of that, however, is out of reach, locked away in the ice or deep underground in aquifers. Only around 1% of the world's total water supply is readily available to sustain all life on Earth."

"Blowhole wave energy could soon be world's cheapest clean power"

"The UniWave sea platform is an artificial blowhole that harvests energy from ocean waves. Independent analysts now predict it'll create some of the cheapest renewable energy on the market – and some of the most reliable and predictable, as well. We first encountered Wave Swell Energy (WSE) and the UniWave back in early 2021. This curious, half-sunken-looking concrete structure is designed to efficiently replicate the shape of a natural blowhole – a rock formation that channels waves in at the bottom and features a hole further up the top. As the waves move into the channel, they push out the ambient air through the hole – sometimes causing water to come spouting out as well."

"Hurricane Ian's exceptional death toll, explained"

"Hurricane Ian is now the deadliest hurricane in the continental United States since Hurricane Katrina in 2005. It made landfall on September 28 along Florida's gulf coast at Category 4 strength, with sustained winds of 155 mph driving a storm surge as high as 18 feet, flinging boats and sweeping homes off foundations. As of Friday morning, officials report that at least 101 people are dead from the storm, 89 of them in Florida — 45 in Lee County, which includes Fort Myers and Cape Coral. More than 60 percent of the deaths were due to drowning. "That's something I've never seen in my 38 years in public safety in Lee County," said Cecil Pendergrass, Lee County Commission chair, during an October 2 press conference."
